Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations are absent, and the description fails to disclose behavioral traits such as side effects (create is destructive, get is read), authentication requirements (beyond schema), or rate limits. The dual-mode operation is mentioned only by name.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loaded, but it merely restates the tool's name. It could be more informative while remaining concise, earning a score of 3.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 7 parameters including conditional requirements (order_id for get, purchase_units for create), no output schema, and no supplementary context, the description is incomplete. The agent would need to rely solely on the schema for usage details.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with all parameters having descriptions. The description adds no additional meaning beyond what is already in the input schema, so a baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Create or retrieve a PayPal order', which is a specific verb-resource combination. While it doesn't explicitly distinguish from the sibling 'paypal_invoices', the resource distinction is implicit in the tool names.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use create vs retrieve, prerequisites, or when to use this tool over alternatives like paypal_invoices. The agent must infer context from parameter descriptions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
